When installed to a computer, OneNote creates a folder «OneNote Notebooks» in Documents, and this is where it saves all notebook and note files. By default, this folder is located here:

C:\Users\UserName\Documents\OneNote Notebooks

OneNote Notebooks

The files in OneNote Notebooks directory have the names of the notebooks which contain files with the names of sections of this notebook.

There are two types of OneNote files:

  • *.one – OneNote file (data file, section file, note file etc);
  • *.onetoc2 – OneNote index file which is responsible for organizing collection of notes and sections in a notebook. Not only does this file include the contents of notes, but it is also important in case you need to recover a notebook, because this file opens a notebook in OneNote.

In addition to the files we have described, there is also an internal recycle bin folder (OneNote_RecycleBin) in the folder of every notebook.
